Cha-cha's dress was a thrift store dress that got a "shelf" bust line made of the hem cut off of one of the longer prom dresses when we shortened it. We glued Dollar Tree carnations to a piece of felt and then sewed them on (always trying to ensure the dresses can be used again for other things!)
Our "Jan" wore padding to make her very curvy. To hide her bra straps we added lots of chiffon at the top and to emphasize her waist we added chiffon at the middle. This was another thrift store dress.
